This is an orbital shaker: There are some DIY ways to make an orbital shaker. One thing an orbital shaker is used for is growing biological samples. In which case control over light, and light cycles, may be important. Jakub Nedbal, Lu Gao and, Klaus Suhling have written up instructions for modifying an orbital shaker […]

OpenRAMAN, a $3000 DIY Raman spectrometer
Raman spectroscopy is a technique in which light from a laser interacts with a sample to shift the laser wavelength. Recording the shifts with a spectrometer gives information about the sample. We’ve covered general cheap spectroscopy more than once here. OpenRAMAN is a project to assemble a Raman spectroscopy setup using about $3000 in (mostly […]
An open source pick-and-place machine for $500
Pick-and-place machines are used to quickly and precisely place electronic components onto printed circuit boards. The open source IndexPnP with software powered by OpenPnP is a new cheap DIY pick-and-place machine. Commercial options cost thousands to tens of thousands of dollars. There are several open source designs already out there, a portion of which are […]
DMCdrive: a $10 micro-drive system for electrophysiology & optogenetics
In the field of neuroscience, micro-drive systems are used to position electrodes in order to make electrophysiology recordings. The DMCdrive is an open-source multi-tetrode for electrophysiology that costs ~$10 per micro-drive. It includes an optical fiber for optogenetic experiments and is demonstrated on freely moving mice. The device is presented in a paper on the […]
